摘要：Vegetation spatial structure significantly influences the composition and regulation of soundscapes, playing a vital role in the ecosystem services provided by urban green spaces. This study investigates the relationship between vegetation spatial structure and Bio-Anthropogenic soundscape, aiming to clarify the underlying mechanisms. In the summer of 2024, we conducted surveys across 52 vegetation plots in 10 central urban parks in Beijing, collecting acoustic data with automated recorders and vegetation structural data using backpack LiDAR. Utilizing Random Forest analysis and structural equation modeling (SEM), we finally evaluated the relative importance and influence pathways of 18 vegetation structural parameters across 4 dimensions: vertical characteristics, horizontal characteristics, heterogeneity characteristics, and porosity characteristics. These parameters were evaluated against 10 soundscape indicators, including four power spectral density (PSD) measures and six acoustic indices (AIS). Our findings revealed distinct responses of acoustic communities and soundscape characteristics to variations in vegetation structure. Notably, the porosity characteristics significantly influenced the distribution of acoustic communities, whereas the horizontal characteristics were comparatively less influential. Additionally, vertical characteristics significantly affected bird vocalization distributions, and heterogeneity characteristics influenced insect sound patterns. Furthermore, the study revealed the impacts of vegetation characteristics on AIS. Besides porosity characteristics parameters, canopy-related parameters, such as canopy cover, canopy relief ratio and average crown width, as well as stand height-related parameters including height kurtosis, maximum height and mean height, significantly influenced soundscape characteristics.
